Abstract

This study investigated the physico-chemical and sensory quality of Doenjang added with red pepper (Capsicum annuum L.) seed. The initial moisture content and salt content of Doenjang were 52.03-53.79% and 13.28-14.05%, respectively. The moisture and salt contents of Doenjang slightly decreased and increased, respectively, as fermentation periods increased. According to increasing fermentation periods, pH of Doenjang showed a little decreasing value although there were no difference between samples with various red pepper seed contents. On the other hand, titratable acidity of Doenjang increased as fermentation periods increased. Also, Doenjang added with red pepper seed had higher titratable acidity value than control Doenjang without red pepper seed. In the color of Doenjang, ‘L’ of lightness, ‘b’ of yellowness, and ‘a’ of redness were decreased as fermentation periods increased. Also, generally, increase of red pepper seed concentration resulted in higher values of redness (a), yellowness (b) and lightness (L) of Doenjang. Also, amino-type nitrogen content, which was 497-623 mg% in initial fermentation period samples, increased to 1,000 mg% for control and to 756~896 for red pepper added at the fermentation 120 days. In the total microbes, total cell count in the Doenjang samples was in the range of $10^7{\sim}10^8$ CFU/g regardless of fermentation periods. In contrast, yeast and mold number of Doenjang samples showed the range of $10^5$ CFU/g at the initial fermentation periods and decreased thereafter. In the sensory evaluation of Doenjang, unique Doenjang flavor increased regardless added red pepper seed as fermentation periods increased.

이 연구는 고추씨가 첨가된 된장의 이화학 및 관능적 품질을 조사하였다. 수분함량은 된장 제조 직후 52.03-53.79%에서 발효가 진행됨에 따라 감소하였고, 염도는 13.28-14.05%에서 발효가 진행됨에 따라 큰 변화를 보이지 않았다. pH는 숙성이 진행됨에 따라 서서히 감소하는 경향을 보였고 고추씨 첨가량에 따라 유의적인 차이를 보이지 않은 반면 적성산도는 발효기간이 증가함에 따라 점차 증가하였고, 고추씨 첨가구가 대조구보다 높은 적정 산도를 보였다. 된장의 색도는 발효가 진행됨에 따라 L값과 b값은 약간 감소하고 a값은 약간 증가하는 경향을 보였는데, 전반적으로 고추씨 첨가량이 많을수록 적색도(+)를 나타내는 a와 황색도(+)를 나타내는 b값과 밝기를 나타내는 L값이 약간 높게 나타났다. 또 아미노태 질소 함량은 된장 제조 초기에 497-623 mg%에서 발효가 진행됨에 따라 서서히 증가하여 발효 120일에 대조구는 1,000 mg%이상, 고추씨 첨가구는 756-896 mg%로 증가하였다. 총 균수의 경우 제조 직후부터 발효 120일까지 고추씨 첨가에 관계없이 제조 직후에는 $10^7{\sim}10^8$ CFU/g의 총 균수에서 발효 진행되면서도 $10^7$ CFU/g을 유지한 반면 효모와 곰팡이 수는 $10^5$ CFU/g에서 $10^3{\sim}10^4$ CFU/g으로 감소하였다. 한편 된장의 관능검사 결과 고추씨의 첨가량에 관계없이 발효가 진행됨에 따라 된장의 고유 향미가 증가되었다.
